24AA014/24LC014

2.0 PIN DESCRIPTIONSThe descriptions of the pins are listed in Table 2-1.

TABLE 2-1: PIN FUNCTION TABLE

2.1 A0, A1, A2 Chip Address InputsThe A0, A1 and A2 inputs are used by the 24AA014/24LC014 for multiple device operation. The levels onthese inputs are compared with the corresponding bitsin the slave address. The chip is selected if the com-pare is true.

Up to eight devices may be connected to the same busby using different Chip Select bit combinations. Theseinputs must be connected to either VCC or VSS.

For the SOT-23 devices up to four devices may be con-nected to the same bus using different Chip Select bitcombinations.

In most applications, the chip address inputs A0, A1and A2 are hard-wired to logic ‘0’ or logic ‘1’. Forapplications in which these pins are controlled by amicrocontroller or other programmable device, the chipaddress pins must be driven to logic ‘0’ or logic ‘1’before normal device operation can proceed.

2.2 Serial Data (SDA)SDA is a bidirectional pin used to transfer addressesand data into and out of the device. Since it is an open-drain terminal, the SDA bus requires a pull-up resistorto VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 400 kHz).

For normal data transfer, SDA is allowed to changeonly during SCL low. Changes during SCL high arereserved for indicating the Start and Stop conditions.

2.3 Serial Clock (SCL)The SCL input is used to synchronize the data transferfrom and to the device.

2.4 Write-Protect (WP)This pin must be connected to either VSS or VCC. If tiedto VSS, write operations are enabled. If tied to VCC,write operations are inhibited but read operations arenot affected.

3.0 FUNCTIONAL DESCRIPTIONThe 24AA014/24LC014 supports a bidirectional, 2-wirebus and data transmission protocol. A device thatsends data onto the bus is defined as transmitter, whilea device receiving data is defined as a receiver. Thebus has to be controlled by a master device which gen-erates the Serial Clock (SCL), controls the bus accessand generates the Start and Stop conditions, while the24AA014/24LC014 works as slave. Both master andslave can operate as transmitter or receiver, but themaster device determines which mode is activated.

24AA014/24LC014

4.0 BUS CHARACTERISTICSThe following bus protocol has been defined:

• Data transfer may be initiated only when the bus is not busy.

• During data transfer, the data line must remain stable whenever the clock line is high. Changes in the data line while the clock line is high will be interpreted as a Start or Stop condition.

Accordingly, the following bus conditions have beendefined (Figure 4-1).

4.1 Bus Not Busy (A)Both data and clock lines remain high.

4.2 Start Data Transfer (B)A high-to-low transition of the SDA line while the clock(SCL) is high determines a Start condition. Allcommands must be preceded by a Start condition.

4.3 Stop Data Transfer (C)A low-to-high transition of the SDA line while the clock(SCL) is high determines a Stop condition. Alloperations must be ended with a Stop condition.

4.4 Data Valid (D)The state of the data line represents valid data when,after a Start condition, the data line is stable for theduration of the high period of the clock signal.

The data on the line must be changed during the lowperiod of the clock signal. There is one bit of data perclock pulse.

Each data transfer is initiated with a Start condition andterminated with a Stop condition. The number of thedata bytes transferred between the Start and Stopconditions is determined by the master device and is,theoretically, unlimited, though only the last sixteen willbe stored when doing a write operation. When an over-write does occur, it will replace data in a first-in first-outfashion.

4.5 AcknowledgeEach receiving device, when addressed, is required togenerate an acknowledge after the reception of eachbyte. The master device must generate an extra clockpulse, which is associated with this Acknowledge bit.

The device that acknowledges has to pull down theSDA line during the Acknowledge clock pulse in such away that the SDA line is stable low during the highperiod of the acknowledge-related clock pulse. Ofcourse, setup and hold times must be taken intoaccount. A master must signal an end of data to theslave by not generating an Acknowledge bit on the lastbyte that has been clocked out of the slave. In this case,the slave must leave the data line high to enable themaster to generate the Stop condition (Figure 4-2).

24AA014/24LC014

5.0 DEVICE ADDRESSINGA control byte is the first byte received following theStart condition from the master device (Figure 5-1).The control byte consists of a four-bit control code; forthe 24AA014/24LC014 this is set as ‘1010’ binary forread and write operations. The next three bits of thecontrol byte are the Chip Select bits (A2, A1, A0). TheChip Select bits allow the use of up to eight 24AA014/24LC014 devices on the same bus and are used toselect which device is accessed. The Chip Select bitsin the control byte must correspond to the logic levelson the corresponding A2, A1 and A0 pins for the deviceto respond. These bits are in effect the three MostSignificant bits of the word address.

For the SOT-23 package, the A2 address pin is notavailable. During device addressing, the A2 ChipSelect bit should be set to ‘0’.

The last bit of the control byte defines the operation tobe performed. When set to a ‘1’, a read operation isselected. When set to a ‘0’, a write operation isselected. Following the Start condition, the 24AA014/24LC014 monitors the SDA bus, checking the controlbyte being transmitted. Upon receiving a ‘1010’ codeand appropriate Chip Select bits, the slave device out-puts an Acknowledge signal on the SDA line. Depend-ing on the state of the R/W bit, the 24AA014/24LC014will select a read or write operation.

FIGURE 5-1: CONTROL BYTE FORMAT

5.1 Contiguous Addressing Across Multiple Devices

The Chip Select bits A2, A1 and A0 can be used toexpand the contiguous address space for up to 8K bitsby adding up to eight 24AA014/24LC014 devices onthe same bus. In this case, software can use A0 of thecontrol byte as address bit A8, A1 as address bit A9,and A2 as address bit A10. It is not possible tosequentially read across device boundaries.

For the SOT-23 package, up to four 24AA014/24LC014devices can be added for up to 4K bits of addressspace. In this case, software can use A0 of the controlbyte as address bit A8, and A1 as address bit A9. It isnot possible to sequentially read across device bound-aries.

24AA014/24LC014

6.0 WRITE OPERATIONS

6.1 Byte WriteFollowing the Start signal from the master, the devicecode(4 bits), the Chip Select bits (3 bits) and the R/Wbit (which is a logic low) are placed onto the bus by themaster transmitter. The device will acknowledge thiscontrol byte during the ninth clock pulse. The next bytetransmitted by the master is the word address and willbe written into the Address Pointer of the 24AA014/24LC014. After receiving another Acknowledge signalfrom the 24AA014/24LC014, the master device willtransmit the data word to be written into the addressedmemory location. The 24AA014/24LC014 acknowl-edges again and the master generates a Stopcondition. This initiates the internal write cycle and the24AA014/24LC014 will not generate Acknowledgesignals during this time (Figure 6-1). If an attempt ismade to write to the protected portion of the array whenthe hardware write protection has been enabled, thedevice will acknowledge the command, but no data willbe written. The write cycle time must be observed evenif write protection is enabled.

6.2 Page WriteThe write-control byte, word address and the first databyte are transmitted to the 24AA014/24LC014 in thesame way as in a byte write. But instead of generatinga Stop condition, the master transmits up to 15 addi-tional data bytes to the 24AA014/24LC014 that aretemporarily stored in the on-chip page buffer and will bewritten into the memory once the master has transmit-ted a Stop condition. Upon receipt of each word, thefour lower order Address Pointer bits are internallyincremented by one.

The higher order four bits of the word address remainconstant. If the master should transmit more than 16bytes prior to generating the Stop condition, theaddress counter will roll over and the previouslyreceived data will be overwritten. As with the byte writeoperation, once the Stop condition is received, an inter-nal write cycle will begin (Figure 6-2). If an attempt ismade to write to the protected portion of the array whenthe hardware write protection has been enabled, thedevice will acknowledge the command, but no data willbe written. The write cycle time must be observed evenif write protection is enabled.

6.3 Write ProtectionThe WP pin must be tied to VCC or VSS. If tied to VCC,the entire array will be write-protected. If the WP pin istied to VSS, write operations to all address locations areallowed.

The WP pin is not available on the SOT-23 package.

FIGURE 6-1: BYTE WRITE

Note: Page write operations are limited to writingbytes within a single physical page,regardless of the number of bytesactually being written. Physical pageboundaries start at addresses that areinteger multiples of the page buffer size (or‘page size’) and end at addresses that areinteger multiples of [page size – 1]. If aPage Write command attempts to writeacross a physical page boundary, theresult is that the data wraps around to thebeginning of the current page (overwritingdata previously stored there), instead ofbeing written to the next page, as might beexpected. It is therefore necessary that theapplication software prevent page writeoperations that would attempt to cross apage boundary.

7.0 ACKNOWLEDGE POLLINGSince the device will not acknowledge during a writecycle, this can be used to determine when the cycle iscomplete (this feature can be used to maximize busthroughput). Once the Stop condition for a writecommand has been issued from the master, the deviceinitiates the internally-timed write cycle and ACK pollingcan be initiated immediately. This involves the mastersending a Start condition followed by the control bytefor a Write command (R/W = 0). If the device is stillbusy with the write cycle, no ACK will be returned. If noACK is returned, the Start bit and control byte must bere-sent. If the cycle is complete, the device will returnthe ACK and the master can then proceed with the nextRead or Write command. See Figure 7-1 for a flowdiagram of this operation.

24AA014/24LC014

8.0 READ OPERATIONSRead operations are initiated in the same way as writeoperations, with the exception that the R/W bit of theslave address is set to ‘1’. There are three basic typesof read operations: current address read, random readand sequential read.

8.1 Current Address ReadThe 24AA014/24LC014 contains an address counterthat maintains the address of the last word accessed,internally incremented by one. Therefore, if theprevious read access was to address n, the nextcurrent address read operation would access data fromaddress n + 1. Upon receipt of the slave address withthe R/W bit set to ‘1’, the 24AA014/24LC014 issues anacknowledge and transmits the 8-bit data word. Themaster will not acknowledge the transfer, but doesgenerate a Stop condition and the 24AA014/24LC014discontinues transmission (Figure 8-1).

8.2 Random ReadRandom read operations allow the master to accessany memory location in a random manner. To performthis type of read operation, the word address must firstbe set. This is done by sending the word address to the24AA014/24LC014 as part of a write operation.

Once the word address is sent, the master generates aStart condition following the acknowledge. Thisterminates the write operation, but not before theinternal Address Pointer is set. The master then issuesthe control byte again but with the R/W bit set to a ‘1’.The 24AA014/24LC014 will then issue an acknowl-edge and transmits the eight-bit data word. The masterwill not acknowledge the transfer, but does generate aStop condition and the 24AA014/24LC014 discontin-ues transmission (Figure 8-2). After this command, theinternal address counter will point to the addresslocation following the one that was just read.

8.3 Sequential ReadSequential reads are initiated in the same way as arandom read except that after the 24AA014/24LC014transmits the first data byte, the master issues anacknowledge as opposed to a Stop condition in arandom read. This directs the 24AA014/24LC014 totransmit the next sequentially addressed 8-bit word(Figure 8-3).

To provide sequential reads the 24AA014/24LC014contains an internal Address Pointer which isincremented by one at the completion of each opera-tion. This Address Pointer allows the entire memorycontents to be serially read during one operation. Theinternal Address Pointer will automatically roll overfrom address 07Fh to address 000h.

Note the following details of the code protection feature on Microchip devices:• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.”
